Fujitsu Proposes To Use Palm Vein Biometric Authentication On Tablets


In the past, biometric authentication technologies were adapted to curb the rise of information leaks and identity fraud. Biometric data has become the leading means in which to verify a person’s true identity. Currently, Fujitsu has developed a biometric scanning technology that employs reading the vein patterns on a user’s palm. They have developed the technology specifically for use with a tablet.

The firm recently unveiled the world’s smallest and slimmest palm vein authentication sensor. The sensor, which is approximately 5mm thick, has been downsized to be able to fit into any tablet device. It has also been upgraded with new image sensors and optical components.

Though only a fraction of its former size, the new sensors still have the original authentication performance as the existing technology. The small size allows for it to be easily deployed to smaller gadgets such as mobile devices, tablets and slate PC’s which themselves are also getting smaller by the minute. New developments also enable the sensor to have an expanded range of application for palm vein verification. With this, larger sets of clients are able to employ secure authentication by using simple operations.

A high performance image sensor plus a large optical area was needed in order to maintain both the high-speed authentication process along with a simple user operation. Having the two seamlessly incorporated seemed to be the greatest challenge when it came to reducing the size of the sensor which consequently led it to be limited to the A4-size notebook PC’s in terms of use. Creating an even smaller version could still be possible but would come at a certain price. A smaller sensor would greatly affect the image quality, which in turn would compromise the data compatibility with existing models.

When compared to last year’s May 2011 Fujitsu palm vein authentication sensor, this one was markedly smaller by around 80% along with a significantly thinner frame of only 5mm. This allows it to be conveniently placed in the slots formerly intended for fingerprint scanners in previous notebook models. The compact size also allows it to be easily incorporated into other mobile devices such as tablets, which are also becoming thinner.
